Which Way to the Cloud?

Understanding SaaS, PaaS & IaaS – and choosing the right fit for your business

By Jo Fuller, Percipient

There’s no denying it — the cloud is no longer a future trend. It’s a business necessity. With the global cloud computing market projected to top $620 billion in the coming years, organisations across every industry are making the leap to cloud-first models. But with multiple options available, the question isn’t should you move to the cloud — it’s how.

At Percipient, we help businesses make that choice with confidence. Here’s a practical breakdown of the three core cloud computing models — SaaS, PaaS and IaaS — to help you decide which approach suits your organisation best.

SaaS – Software as a Service

SaaS is the most common route to the cloud for modern businesses. In this model, you access ready-to-use software over the internet, managed entirely by the software provider.

Why it works:

  • No installations or manual upgrades
  • Rapid deployment and scalability
  • Minimal IT involvement
  • Automatic updates and security patches
  • Frees up internal teams to focus on strategy, not support

Ideal for: Organisations seeking agility and simplicity in accessing software like accounting, CRM, or HR systems, without the overhead of maintaining them.

PaaS – Platform as a Service

PaaS provides a cloud-based framework that enables developers to build, test, and deploy custom applications. It provides the infrastructure and tools needed to accelerate software development.

Why it works:

  • Accelerates application development
  • Reduces time-to-market
  • Scalable and cost-effective
  • Offloads infrastructure management
  • Supports customisation without the complexity

Ideal for: Businesses with in-house development teams looking to build tailored solutions quickly and securely, without managing backend infrastructure.

IaaS – Infrastructure as a Service

IaaS delivers virtual computing resources over the internet, replicating a data centre in the cloud. This option provides full control of your infrastructure without requiring physical hardware.

Why it works:

  • Complete control over infrastructure
  • Pay-as-you-go model reduces costs
  • Scales easily with your needs
  • Eliminates the need for on-site data centres
  • Customisable to fit complex IT strategies

Ideal for: Larger organisations or those with specific regulatory or architectural needs who want the flexibility of self-managed infrastructure without capital costs.

The Cloud is Not One-Size-Fits-All

Each approach—SaaS, PaaS, and IaaS—offers its own advantages. The right path depends on your business goals, internal resources, and the level of hands-on involvement you want to have with managing infrastructure or development.

Regardless of where you are in your cloud journey, there’s a model that suits you. With the proper guidance, your move to the cloud can deliver significant value, from cost savings to increased innovation speed and operational agility.
